SISTR2 scores by functional annotation.

SISTR2 was used to infer the distribution of selection coefficients at different classes of trinucleotide STRs overlapping different genomic annotations. Columns give the repeat unit length (in bp), optimal allele length (in rpt. units), category (coding, intron, 5’UTR, 3’UTR, promoter, intergenic), and number of loci considered for each inference. The last three columns show the estimated values for the gamma distribution parameters a and b as well as the corresponding mean estimated selection coefficient (computed as a*b). (XLSX)
